`This invention relates toa hand operated clipper especially designed'Vand adapted forv removing the hair under the arm pits.

f For various reasons,j1t 1s desirable to use (6 hair'clippers'V for thepurpose of removing Y because the known clippers are so constructed .10and so operated as to be incapable of following the contour of the fleshinthe region'of the armpits and also becauseall prior types of clippersare designed'forj-use with one hand only. Concerning the latter featureof the prior types of hand clippersit is to be noted that such clippershave a stationary handle and a* movable handle. Thi-s arrangement makesit possible to operate the clippers with one hand only and if suohaclipper is shifted A to the other hand it will be found practicallyimpossible to effectively use the clipper for the reason that theclipperrmay not'be held steady while operated. y

Among the importantobjects of the pre-s.-l ent invention are to providea hand operated clipper which is adapted for convenient and effective.operation kwithj ,either hand and which is so constructed and organizedthat it readily and easilyv follows the contour ofthe flesh in theregion of the arm pits and does so in such'a manner as to effect veryclose clipping of the hair without any pulling and without any abradingor irritating action on the liesh.

clipper is provided which consists broadly of coacting blades mounted onvone end of a handle memberin such manner that when ,4 the clipper is inuse it operates with a hoe Y Y in the conventional clippers. Thisfeature is one of the principalfactors inthe ability of the clipperV tofollow the contour ofthe flesh in the region of the arm pits and toeffec-V tively remove or clip hair in such regions. In

. addition the operating mechanism provided for the clipper blades, themanner of its or- In carrying outithe present invention a hair cganization with the handle and with the blade, is such as to provide foreasy and convenient .operation of the clipper with either hand.

Other objects and advantages reside in eertain novel features of theconstruction, arrangement and combination of parts which will behereinafter' more fully described and particularly pointed out in theappended claims, reference being had to the accom- .panying drawingforming a part of this speciiication, and in which:

Figure 2 is a view in section on line 2 2 of Figure l, parts being shownin'elevation for the sake of simplicity and illustration;

Figure 3 is a top plan view of the clipper, parts being broken away andparts being shown in section for the sake of illustration; and

Figure 4 is a view in horizontal section taken on line 4 4 of `Figure 2.

Referring to the drawing, numeral l designates generally a handle whichincludes an outer part or casing 2 shaped to be conveniently gripped inthe hand and having titted'and releasably secured by means of a lockscrew 5. The shank 4 projects above the upper end of the casing orcovering 2 and hasv a reduced extension or post ,64 formed integraltherewith.

The fixed blade 7 has an internally threaded opening 7 thereinand with this internally threaded opening 7 the threaded outer end 5 ofthe a. socket 3 in which a shank 4 is frictionally i --L- Ajsleeve '12is ifitted 1ontheJi-ifine'r.smooth,y portion of the post 6 foroscillating movementv mit thecmovable blade tohave the requisite lfreedomjofgmovementi ffAlong itSrear edge;y

Along with these advantages the clipper is simple and of durableconstruction, its parts are easily accessible for cleaning andlubrication, replacement and repair and it lends itself to economicalmanufacture by facilities and from materials ordinarily obtainable.While a clipper embodying the present invention is especially designedand adapted for removing hair under the arm pit, in general this clippermay be used to advantage in places where a regular standard type of handclipper may not be effectively or satisfactorily employed.

rEhe invention claimed is:

2. A hand operated clipper comprising a handle, a fixed blade extendingtransversely to the handle and secured thereto adjacent one end thereof,a movable blade coacting with the fixed blade, a tension member mountedon the handle, means for forcing the tension member against the fixedblade and for biasing it to bear against the movable blade to cause themovable blade to engage the fixed blade with the proper tension andmeans mounted on the handle for operating v the movable blade.

3. A hand operated clipper comprising a handle, a separate fixed bladeextending transversely of the handle and secured there to near one endthereof, a separate movable blade coacting with the fixed blade, asleeve mounted for oscillation on the handle and a driving membersecured to the movable blade and interconnected with the sleeve so as tobe oscillated thereby.

4. A hand operated clipper comprising a handle, a fixed blade secured tothe handle near one end, a movable bladecoacting with the fixed blade, atensioning member for urging the blades to engage each other with theproper pressure, a sectional housing secured to the fixed blade andenclosing the fixed and movable blades and the tension member andoperating mechanism for the movable blade including a sleeve mounted onthe handle outside of the housing` and having a portion projectingtherein and a driving connection between said portion and the movableblade.

5. A hand operated clipper comprising a handle having a post extendingaxially from one end thereof, a blade fixed to one end of the post andextending transversely thereto, a sleeve rotatable on the post, adriving member connected to the sleeve, a movable blade secured to thedriving member and coacting with the fixed blade, and a spring tensionmember fixed to the post and bearing up against the movable blade tourge it to engage the fixed blade with the proper pressure.

6. A hand operated clipper comprising a handle having a post extendingfrom one end thereof, a blade threadedly connected to the outer end ofthe post and extending transversely thereto, a sleeve rotatably fittedon the post, a driving member connected to the sleeve, a movable bladesecured to the driving member and coacting with the fixed blade, aspring tension member having one end mounted on the post and one endcooperable with the movable blade and a nut threaded on the post toclamp the spring tension mem` ber and fixed blade in operative position.

7. A hand operated hair clipper comprising a handle having a postextending axially therefrom, a fixed blade secured adjacent the outerend of the post, extending transversely thereto and having teethdisposed in an arc struck from the axis of the post as a center, amovable blade mounted for oscillatory movement about the post as an axisand having teeth disposed in an arc struck from the post as a center andcooperable with the teeth of the fixed blade, the axes of the teeth ofeach blade being parallel and means for Inoving the movable blade backand forth in au are which has the post as a center.

In Witness whereof, we hereto affix our signatures.
